Greek key topology


The prealbumin monomer is a &beta;-sandwich composed of an antiparallel and a mixed &beta;-sheet. It forms a dimer with the mixed &beta;- sheets associated to a large transmolecular sheet. Topology diagram of the monomer:

A Greek key consists of 4 antiparallel &beta;-strands in the order bcda, i.e. the the 1st and 4th strand are adjacent and the 2nd and 3rd strand form a &beta;-hairpin.
